Teaching Methods

Theoretical classes, using audiovisual means, with detailed exposition of concepts, principles and fundamental theories and with the resolution of basic practical exercises that demonstrate the practical interest of the subject and exemplify its application to real situations. Practical laboratory classes, where the teacher should support the students in their execution of the practical assignments. The evaluation consists of a final exam and practical assignments. The exam will include theoretical questions, in which students will have to demonstrate the comprehension of the subject.

Learning Outcomes

This course aims to provide students with advanced knowledge and competences to integrate and connect applications and systems with particular attention to the following cases:

- interconnection of different modules of the same large application, with particular emphasis on aspects such as performance, security and monitoring;

- integration of computer applications from different sources, within the same organization;

- integration of computer applications between different organizations.

Unfortunately, many of the real systems tend to use ad hoc solutions that are extremely fragile and ill-prepared to evolve. To solve these problems, students should learn how to integrate systems in a structured way. This course has a strong emphasis on integration with middleware systems, in particular, using approaches such as Service Oriented Architectures (SOA), Enterprise Service Buses (ESB), and reactive programming.
